Abstract

The implantable CNT-based sensor is suggested to
detect CSPGs which is main compositions of glial scar which
inhibit the axonal regeneration after spinal cord injury. The
suggested sensor is fabricated using spin-coated polyimide and
patterned by MEMS process. Multiwalled CNT networks are
formed by air spray method on the interdigitated sensor
electrodes as the sensing element of CSPGs. The feasibility of the
fabricated sensor is successfully confirmed in vitro by measuring
the resistance change of CNT networks versus various CSPGs
concentrations. The results show that the suggested sensor
accurately detects the low CSPGs concentration to sense the
regeneration-inhibitory effect of CSPGs.
